Definition
A routine inspection of the operational status of the board, which is based on 14 inspections per day, and is rated in three colours.
In detail
Daily kanban audit is a daily check of the kanban system against 14 check items, using a three-color criterion (red, yellow, green) to assess operational status. It addresses the problem of kanban system failure, ensuring the accuracy of kanban quantities, signals, and processes. Its difference from the kanban system itself is that it is a maintenance tool, not a production control tool. Typically, the output is audit records and issue lists for continuous improvement.
Example in practice
In the assembly workshop, the team leader conducts a daily pre-shift check of kanban cards, signal lights, and inventory locations according to a checklist. One day, a kanban card is found missing, marked in yellow, and immediately replenished while investigating the cause. Through daily audits, the kanban system operates stably, and stock-out events decrease.
